Enhanced grenade launcher - big shot

Abstract

An electrical system which serves to control the firing of multiple grenadeaunchers. The system generates multiple coded tone pairs for up to sixteen launchers which are provided to the launchers through a +28VDC line connected to the vehicular power supply. The tone pairs are decoded enroute to each launcher which exercise a firing circuit triggering the grenade launcher's firing squib causing the grenade to launch.

What is claimed is: 
     
       1. A fire control system for simultaneously firing a plurality of grenade launchers comprising: means to generate multiple respective tone pairs each for a respective selected grenade launcher;   means to select up to sixteen of said multiple respective tone pairs;   means to pass the selected tone pairs to the launchers;   means operatively connected to said launchers to decode the tone pair for a selected respective launcher; and   means to activate a respective squib of a respective launcher to fire such selected respective grenade launcher.   
     
     
       2. The fire control system of claim 1 wherein the means to generate multiple tone pairs for selected grenade launchers is a crystal controlled tone generator. 
     
     
       3. The fire control system of claim 1 wherein the means to select up to sixteen tone pairs is a selector switch which grounds the appropriate terminals of the said tone generator. 
     
     
       4. The fire control system of claim 1 wherein the means to pass the tone pairs to the launchers is via a +28 VDC line connected to a vehicular power supply. 
     
     
       5. The fire control system of claim 1 wherein the means to decode the tone pair for a selected launcher is a crystal controlled decoder. 
     
     
       6. The fire control system of claim 1 wherein the means to activate the squib to fire the selected grenade launcher is an optically triggered triac. 
     
     
       7. The fire control system as in claim 1 in which the means to generate multiple tone pairs for selected grenade launchers is the crystal controlled tone generator NTE 1690. 
     
     
       8. The fire control system as in claim 1 in which the means to decode the tone pair for a selected launcher is the crystal controlled decoder CS202. 
     
     
       9. The fire control system as in claim 1 in which the means to activate the squip to fire the selected grenade launcher is the optocoupler MOC 3010. 
     
     
       10. The fire control system as in claim 1 which allows for selectivity of grenade launchers without changing any of the existing wiring harness.
